SASH-FASTENER.

srncxrrcanon forming part of Letters Patent No. 376,654, dated January 1-1, 1888.

V I Application filed September 15, 1887. Serial No. 249,885. (No inodeL) T0 (1 whom it may concern:

- Be itknown that I, KATE DUVAL HUGHES, a citizen of the United States, residing in the city of Washington, in the District of Columbia, have invented a new and useful Combined Window-Sash Fastener and Holder, of which the following is a specification.

It is the object of the present invention to provide means by which the upper and lower sash of windows may be respectively lowered and raised 'to a limited extent and secured from further opening from the outside, thus preventing unauthorized persons from gain ing ingress by increasing the size of the opening either at the top or bottom of the sash.

In the'drawings, Figure 1 represents the window in vertical section, the sash being also shown in section with one form of mylocking device. Figs. 2 and 3 represent details. Figs.

4 and 5 represents modifications of these details. Fig. 6 represents another arrangement of the locking-chain, differing slightly in conneetion with that shown in Fig. 1.

In the drawings, A represents the frame of the window, and B represents the sash. These sash may be of ordinary construction, and may be provided with weights or without them, it being understood that my attachment will be made complete in itself and may be applied by every householder.

As shown in Fig. 1, I attach to the windowframe upon the inside a staple, a, which may be attached by means of a plate and screws, as shown in Fig. 2, or by a screw-shank, as shown in Fig. 4. I preferably secure this stapleat a point below the meeting line of the sashes, for a purpose hereinafter set forth.

To the upper end of the lower sash, upon one side, I attach a hook, b,which may have a fastening plate, such as that shown in Fig. 3, or a screw-shank, such as shown in Fig. 5, and between the staple wand the hook b, I connect a section of chain, c. This chain, which is to be made with open links, may be of any convenient length, and, as it is connected byv means of a hook atone end, it will be understood that any length of the chain may be used by connecting it at any intermediate link with the hook upon the sash,'and the window may be raised to a height corresponding to the length of the chain and the position of the staple a. When the lower sash is thus raised, as shown in Fig. 1, it will be'seen that-the section of chain 0 will allow no further movement in an upward position, practically locking the sash so far as upward movement is concerned, while perniitting it to be freelyclosed. In ordinary cases the friction of the sash will hold it in a raised position against the sides of the frame, or when used with weighted sash the weights will keep itin this position. When the lower sash is lowered, the section of chain a can be detached from the hook I) at its end link, and the'coupling may be made short enough to lock' the. sash in aclosed position. v

The upper sash is provided with a like hook, bf, which may be attached in either of the ways described, and the section ofchain c extends from the staple a to this hook, crossing over the top of the lower sash. When the:

tion, and it is thus securely locked fromfurther downward movement, though being free to move upward. In orderto preventany wear to the upper part of the sash, a piece of. felt or other material may be placed beneath the chain.. r

In Fig. 6 I have shown a single chain instead of the two sections, one end being connected with the staple a, and an intermediate link being connected with the hook of the lower sash, andone of the end links being fastened to a hook on the upper sash, this being an equivalent arrangement of onechain being provided in place of two.

I claim as my invention In a window-sash fastener, the combination; of a staple attached to the frame below the meeting-rails of the sashes, a chain secured to the staple, and a scroll-shapedhook attached to the sash, said chain having open linksand being capable of attachment to the hook by means of'its various links, substantially as described- KATE DUVAL HUGHES.
